Digital impressions are increasingly used to manage Cleft lip and/or palate (CL/P), potentially offering advantages over traditional methods. This laboratory investigation sought to evaluate the impact of scanning tip sizes, different scanners, and scanning strategies on intraoral scanning in neonates with CL/P. Ten soft acrylic models were used to simulate the oral anatomy of neonates with CL/P, evaluating parameters such as the ability of different scanning tips to capture alveolar cleft depth, scanning time, number of scan stops, and scan quality. The study utilised various scanning tips, including the Carestream normal tip, Carestream side tip, and Trios 4 scanner tip to assess the alveolar cleft depth measurements. The Trios 4, Carestream, and iTero scanners were evaluated for the time taken, number of scan stops during cleft-unobstructed scanning and cleft-obstructed scanning. The quality of all scanned images was analysed. The findings showed comparable accuracy in capturing alveolar cleft depth with the three-scanning tip ( > 0.05). Scanning time and the number of scan stops did not significantly differ across the three scanners and various scanning strategies employed ( > 0.05). However, scanning with the cleft obstructed required less time and resulted in fewer scan stops compared to cleft -unobstructed scanning. Despite these results, all scanners failed to record the deepest part of the alveolar cleft, highlighting a limitation in current scanning technology for neonates with CL/P. The study recommends enhancing intraoral scanning in this population by adjusting tip size, improving clinician training, optimizing protocols, and conducting further research to improve techniques.
数字印模越来越多地用于治疗唇腭裂（CL/P），与传统方法相比可能具有优势。这项实验室研究旨在评估扫描头尺寸、不同扫描仪以及扫描策略对唇腭裂新生儿口腔内扫描的影响。使用十个软质丙烯酸模型模拟唇腭裂新生儿的口腔解剖结构，评估不同扫描头捕捉牙槽裂深度的能力、扫描时间、扫描中断次数和扫描质量等参数。该研究使用了各种扫描头，包括Carestream常规扫描头、Carestream侧面扫描头和Trios 4扫描仪扫描头，以评估牙槽裂深度测量结果。对Trios 4、Carestream和iTero扫描仪在无裂隙扫描和有裂隙扫描期间的扫描时间、扫描中断次数进行了评估。分析了所有扫描图像的质量。研究结果表明，三种扫描头在捕捉牙槽裂深度方面具有相当的准确性（P>0.05）。三种扫描仪以及所采用的各种扫描策略在扫描时间和扫描中断次数上没有显著差异（P>0.05）。然而，与无裂隙扫描相比，有裂隙扫描所需时间更少，扫描中断次数也更少。尽管有这些结果，但所有扫描仪都未能记录牙槽裂的最深部分，这突出了当前唇腭裂新生儿扫描技术的局限性。该研究建议通过调整扫描头尺寸、加强临床医生培训、优化方案以及开展进一步研究以改进技术，来提高这一人群的口腔内扫描效果。
